Wow, I don't know what happened, but this week we got so many posts. I had a really hard time to keep this newsletter at a reasonable size.
I saved some of the posts for later, in case next week, when the weather improves, the authors will go out instead of publishing articles.
Go, enjoy the articles...

Announcements

.... This reminds me if we could marry Padre with PDL, that could be an interesting step towards providing an alternative to Matlab.

I especially liked the part: 'Basically, we ported the Perl programming language to the ADX application processor so that you can use APIs to control application delivery with a script. This means you get all the Perl goodness that you know and love for writing custom scripts to read or write layer three to seven headers based on your particular application needs.'

Michael G Schwern describes how he thinks developers should be interview by potential employers. I am not sure if he talks from experience as an interviewer or as someone who is applying for a job. In either case interesting point.

|
by Neil Bowers (NEILB)
Neil Bowers describes the process of taking over maintenances of a CPAN module.
|

Testing
|
In response to an article by Jonathan Swartz arguing against running tests on installation, chromatic describes why he runs test and why he was looking for ways to improve the speed of testing. Being able to run the tests after installation would be nice and would be able to help in case we upgrade a dependency that breaks an already installed module.

Joseph Walton, author of XML::Writers takes the data from CPAN testers and shows some interesting graphs about the relation ship between the release dates of perl, XML::Writer and the respective test reports on CPAN Testers.
|
|
Refactoring
|
'don't assume the author is an idiot'. An obvious refactoring and an educational post goes wrong. There is a certain relaxing feeling that even people like Schwern can make mistakes. Sometimes.

Code

Dmitry Karasik shows and explains how to write a udp_server using his IO::Lambda module.
|
|
Small but useful script for Perforce users.

Tim Heaney (oylenshpeegul) uses Google::Directions to find out how could the president of USA visit the workshop. I am quite sure he will have to pick an alternate route, now that the planned one was exposed to dangerous Perl Hackers.

An article by Douglas from Shutterstock about two surprising features of Perl that can easily trip programmers. Some interesting comments included.
